Abstract: Electrochemical and thermal hydrogen storage alloy compositions that provide superior performance, including an electrochemical hydrogen storage alloy that provides superior low temperature discharge characteristics. The alloy compositions include microstructures in the interface region that are highly porous and that include catalytic metallic particles. The microstructures include a large volume fraction of voids having spherical or channel-like shapes and are sufficiently open structurally to facilitate greater mobility of reactive species within the microstructure and in the vicinity of catalytic metallic particles. Greater accessibility to reactive sites accordingly results. The greater mobility of reactive species and/or the greater density of catalytic particles lead to faster kinetics and improved performance (e.g. higher power), especially at low operating temperatures.

Abstract: The present invention is a method of data storage using a phase-change memory clement operating within its amorphous phase. The element stores at least one bit of data upon the application of a pulse that resets the element to one of at least a first resistance state and a second resistance state. Since the threshold voltage of a memory element varies linearly with its programmed resistance, the stored data can be read by the application of one or more discriminating voltages to the element. The current flowing through the element is limited to prevent a phase change when an applied discriminating voltage is greater than the threshold voltage. When the applied discriminating voltage is less than the threshold voltage, current flowing through the memory element is not limited. Based upon these current outputs, the resistance state of the element is determined.

Abstract: A fuel cell utilizing parallel flow of a hydrogen stream, an oxygen stream, and an electrolyte solution with respect to the electrodes, while maintaining mechanical support within the fuel cell. The fuel cell utilizes framed electrodes to maintain a high air flow rate and low pressure throughout the fuel cell. The fuel cell is also designed to maintain mechanical support within the fuel cell while the electrodes expand and contract in response to the absorption of oxygen and hydrogen. Gas is predistributed by the compression plates and frames to supply the electrodes with high concentrations of oxygen from air.

Abstract: A hydrogen gas cooled hydrogen storage element which includes a hydrogen storage alloy material in which hydrogen flow channels are provided. The flow channels provide pathways through the hydrogen storage material to allow for high speed hydrogen gas flow. A portion of the high speed hydrogen flow is stored within the storage material which releases its heat of hydride formation. The remainder of the hydrogen flows through the hydrogen storage material at a sufficient mass flow rate to remove the heat of hydride formation. The unit also includes an encapsulant to prevent any loose particles of the storage material from becoming entrained in the high flow rate hydrogen.

Abstract: A hybrid vehicle having a hydrogen powered internal combustion engine employing a cylinder deactivation strategy during idle or light load conditions. A continuous stream of air is supplied to the hydrogen internal combustion engine. A control system responsive to engine speed and accelerator pedal position calculates a specific amount of hydrogen to inject into the continuous air stream. The resulting stream is combusted in the engine to provide power to the vehicle. During idling or light load conditions, the hydrogen supply to one or more cylinders may cease while maintaining the flow of air to the cylinders. A rechargeable battery and an electric motor receiving power from the battery are used to supplement the hydrogen powered internal combustion engine.

The element includes a phase change material that may be reversibly transformed between its crystalline and amorphous states. By forming a gradient in crystallinity, a phase taper may be stored in the phase change material of the instant element. The phase taper provides control of the phase angle of reflected or reradiated electromagnetic radiation. An incident wavefront of electromagnetic radiation interacts with the instant element and is reradiated with controlled propagation characteristics imposed by the stored phase taper. The instant element may provide non-specular reflection, beam steering, focusing, defocusing, symmetrical and asymmetrical cross section effects, and wavefront correction. In a preferred embodiment, a pattern of amorphous marks is formed within a crystalline matrix of phase change material.
